Since 2016, the Environmental Protection Agency has developed a national-level station for data collection, station maintenance, and data quality assurance, etc.through the "Air Quality Monitoring Station Data Collection and Processing System Project", establishing a foundation for station data collection and integration.In 2019, through the "108-109 Environmental Internet of Things-Intelligent Measuring Station Management Plan", the collection of relevant data from the National Environmental Monitoring Station of the Environmental Protection Agency (added new environmental and information equipment) were strengthen. The industrial CpK method were introduced to analyze relevant data, establish a quick screening mechanism for status abnormalities, assist relevant station personnel to carry out operations such as instrument maintenance, repair, and review, build a foundation for the information flow and operation flow of the station, and laying the foundation for the operation and management of the next generation station.
The method of collecting and reorganizing station data integrates the transmission methods of old and new instruments at each station, such as traditional analog RS232 port and digital transmission, and uses TCP/IP protocol to convert relevant signals into packets and send them to the central system. In addition, in order to ensure that the data collection and processing system of the Environmental Protection Agency is competent and plays the role of a stable data source, it is necessary to continue to strengthen the current station data collection service and data quality functions, to gain improve data availability, integrity. Also, effectively provide front-end smart application systems accessing sensor data for value-added, management and decision-making applications.
This project continues to collect relevant information such as the measuring station server, network, measuring station environment, etc., and designs a real-time serial connection module for measuring station instrument information to provide an integrated display platform for air quality monitoring information, which can instantly query the measuring station instrument information, and increase Instrument maintenance efficiency; manual sampling function module design, integrating the newly purchased PM 2.5 manual sampling instrument, developing a data transmission module, each batch of sampling records can be smoothly transmitted back to the central database, providing a Web API interface, allowing air The quality monitoring information integrated display platform can capture the sampling records of each measuring station in real time; the measuring station camera backup module design adds a measuring station image return backup mechanism. When the measuring station host needs to be shut down for maintenance, image recovery can be started. The transmission backup mechanism transmits the measurement station images back to the center; the system operation record query page provides the measurement management platform manager with the function of querying user operation records to avoid operational errors; the measurement station bulletin board function design provides measurement station managers with , can announce the relevant information of the measurement station on the measurement management platform, and remind the measurement station maintenance personnel to pay attention; the DAS/IOMS version automatic monitoring function is designed to automatically transmit the DAS and IOMS system versions of the measurement station back to the measurement management platform, and the operating system version of the measurement station can be queried. status; in addition, the test station server host operating system was upgraded to Windows Server 2019 and added to the department's network domain to strengthen information security management to achieve the performance of intelligent management of the test station.
